Whatever spiral pipe production process you prefer: the conventional 1-stage or 2-stage (offline) process, SMS gives you ingenious solutions to help you compete and succeed.
That includes not only the core process equipment for pipe forming and welding, but also the upstream and downstream process steps for all your turnkey projects.

Comprehensive welded pipe technology

2-stage offline production process

There are two key advantages of 2-stage spiral pipe welding machines: improved quality and higher productivity. Core components are the quick forming stations and the high-performance finish-welding stands.

Emergency Support

Remote service

Remote access to the machine control system for fault analysis is possible only after authentication by the customer. Direct analysis and evaluation of the operating parameters are performed online by the SMS Service employees. They can easily identify defects and malfunctions and initiate measures for fault elimination. Remote access also allows the system software to be updated. Naturally, the installation of the necessary hardware and software for the remote access is already included in the remote service.
